SMOKE WASHER OB PURIFIER.

Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed June 2,1917. Serial No. 172,514.

Washers or Purifiers, of which the following is a specification.

This invention is a Washer or purifier for smoke and has for its object to provide an improved device for preventing the charge from a stack of thick black smoke which is prohibited by many municipal regulations.

The apparatus comprises a conduit or chamber through which the smoke flows, and this chamber has therein a series of battles of different kinds forming staggered )assages, and means are provided for flowlng water down the outer surface of the battles, and in the passages therebetween, whereby the dirty smoke passes through a water spray and across wet surfaces, which washes out the soot, and finally the washed smoke is subjected to the action of steam to correct any dark color due to remaining sooty particles.

The invention is illustrated in the accompanying drawings in which- Figure 1 is a side elevation of the washer;

Fig. 2. is a vertical longitudinalsection thereof;

Fig. 3 is a section on the line 3-3 of Fig. 2;

Fig 4 is a section on the lines-4 of Fig. 2; and

Fig. 5 is a vertical cross section on the line 55 of Fig. 2.

Referring specifically to the drawings, 6 indicates a casing or conduit for the smoke, communicating at one end through an elbox 8 of the boiler and at the other end through a pipe 9 with the smoke stack 10. This casing or conduit is shown as rectangular in.- cross section, but may be of any shape desired. Mounted upon or forming a part of the casing is a water tank 11 which covers the top of the casing and has a water inlet pipe 12. The bottom of the casing is inclined downwardly toward the stack, and forms a bottom water chamber 13, from which water overflows a ledge 11 to a discharge pipe 15 through which the water and collected soot go to waste.

Extending vertically across the casing 6,

dis-

within the same, are a series of rows of hollow baffles 16 the upper ends of which commun1catesthrough openings 17 with the water tank 11 and the lower ends of which open into the settling chamber 13. These rows are spaced apart, and in the spaces therebetween are a series of rows of corrugated sheet metal baflies 18, which stand vertically. The hollow baflies 16 areinclined one way with respect to the direction of flow of smoke through the conduit, and the sheet metal baflles 18 are inclined the other way,

so that a plurality of 'zig-zag passages are produced, between the baffles, through which the smokeflows from the inlet to the outlet. Water is flowed over the surfaces of these baflles. With respect to the hollow baffles, row of small holes 19 near the upper end of each wall, and with respect to the sheet metal baflies 18, water is supplied through rows of small holes 20 in the bottom of tank 11, these holes being located closely adjacent to the upper edge of-the baflles referred to. WVater thus drips down the outer surfaces of the baffles and washes the soot out of the smoke as it flows therebetween.

A further supply of water is provided in the passages between the bafiies, by means of a series of water pipes 21, bent to conform to the zigzag shape of the passages and located in the upper part thereof. These pipes have spray holes 22 in the lower sides thereof, and water discharged thereover is sprayed 1nto the passages and wash the smoke passing therethrough. The pipes are supplied hrough a branch pipe 23 from the water main 12'.

' Finally, in the outlet connection 9 I provide a steam pipe 30 with numerous small perforations 31 through which a spray of steam is discharged into the smoke as it enters the stack, to give it a light or grey color.

\Vhen sooty smoke is passed through the apparatus above described the soot is washed therefrom by the action of the water flowing down the surfaces of the baffles and sprayed into the passages therebetween, and the water flows into the lower pan 13 and with the collected soot overflows to the escape pipe 15. It may be noted that the edge of the overflow ledge 14 is sufliciently high to form a water seal for the lower ends of the baflles, so that the smoke is confined t0 the ziz-zag passages between the same.

I claim:

1. A washer for smoke or the like, comprising a conduit for the smoke, a plurality of vertical hollow baflles extending across said conduit, and means to flow water down the outer surfaces of said bafiies.

2. A washer for smoke or the like, comprising a conduit for the smoke, a plurality of hollow vertical baflles disposed within the walls of said conduit, said baffles having openings through the same to feed water from the inside to the outside of said battles, to moisten the external surfaces thereof.

3. A washer for smoke or the like, comprising a horizontal conduitfor the smoke, a plurality of hollow bafiies having perforations through the walls thereof, a water tank on top of the conduit, communicating with the interior of the battles, and a discharge outlet for water at the bottom of the conduit.

4., A washer for smoke or the like comprising a horizontal conduit for smoke, a

series of vertical baflles within said conduit,

forming zig-zag passages throughthe same, and means to spray water into said passages.

A Washer for smoke or the like comprising a conduit having a water collecting pan in the lower part thereof, a series of vertical bafiles extending across said conduit and depending into the pan below the water level therein, and means to feed water into the passages between the battles.

6. A washerfor smoke or the like, comprisinga conduit'having a water collecting pan in the lower part thereof, a series of vertical baflles extending across said conduit and depending into the pan below the water level therein, and means to feed water into the passages between the baffles, said means including a series of pipes extending lengthwise in the upper part of the passages.

In testimony whereof, I do aflix my signature in presence of two witnesses.
